1 Pesticides 3.0 New contaminants What are we talking about? And how to evaluate the new substances? Dr. Silke Bruns Lach & Bruns Partnerschaft

2 What are we talking about? Substances such as QAC (diary products), Nicotine (tea), DEET (mushrooms), Chlorat (fruits/vegetables), Perchlorat (vegetables) stimulate the question: Do they have to be evaluated like pesticide residues according to Regulation (EC) No 396/2005? Substances which are NOT applied against pests - but enter the food chain via contamination: How to evaluate them from the food safety perspective? 2

3 So the overall question is: Which rules do I have to consider when I find the New substances in my food products? 3

4 European Legislation The rules (to be applied) are linked to the cause: - Pesticide residues are resulting from the use of a plant protection product. - Biocide residues result from the use of a biocidical product in or on products of plant or animal origin. - Residues of veterinary medical products result from the use of pharmacologically active substances which remain in food obtained from animals. 4

5 So in terms of pesticide residues, what does this mean? 5

6 Regulation (EC) No 396/ on maximum residue levels of pesticides in or on food and feed of plant and animal origin à applies for ALL food products (EU): also for à Maximum Residue Levels (MRLs) are laid down for well-defined food-pesticide combinations (à Annex II of 396/2005) à Where the Regulation's annex contains no MRL, the default value (acc. to Art. 18 of 396/2005) applies: 0,01 mg/kg à In general, no pesticides have to be expected in organic food products. But in case levels of pesticides are detected: They must not exceed the limit values (MRL) laid down in Reg. (EC) No 396/2005! (à NOT MARKETABLE) 6

7 Regulation (EC) No 396/2005 Art. 3 (2c), Regulation (EC) No 396/2005 defines pesticide residues as follows: "residues, including active substances, metabolites and/or breakdown or reaction products of active substances currently or formerly used in plant protection products., including in particular those which may arise as a result of use in plant protection,.. à Prerequisite for application Reg. (EC) No 396/2005: Actual use of substance as a plant protection product 7

8 So the overall question is: Which rules do I have to consider when I find the New substances in my food products? 8

9 According to the System of European Legislation the cause/source link of a substance should decide, which rule (Regulation) to apply. 9

10 The pesticide regulation 396/2005 is only valid if you find something in your food product, which is a residue of a plant protection product! So if I find something which is NOT a residue of a plant protection product, then the pesticide regulation 396/2005 is NOT valid. YES!!! 10

11 Regulation (EC) No 396/2005 But... the cause/source link is some kind of abandoned : Regulation (EC) No 396/2005 goes beyond plant protection products although this is in contradiction with the title of the Regulation (Regulation. on maximum residue levels of pesticides): "residues, including active substances, metabolites and/or breakdown or reaction products of active substances currently or formerly used in plant protection products., including in particular those which may arise as a result of use in plant protection, in veterinary medicine and as a biocide. 11

12 What does this mean????? 12

13 What does this mean? - As residues of biocides and veterinary medicines are NOT residues of plant protection products, the application of Regulation (EC) No 396/2005 goes beyond pesticides. - This regulation thus can be applied for residues of other products as well. - Substances found in food products can have other sources than the use of plant protection products (like Perchlorate, Chlorate, QAC etc.). BUT also in such cases, Regulation (EC) No 396/2005 might be applied. 13

14 What does this mean? The clear distinction between pesticide residues of plant protection products and other substances (like f. ex. contaminants, which results from an unintended contamination - f. ex. via the production process) is softened and not so clear anymore. Regulation (EC) No. 396/2005 Pes$cide residues Biocides / veterinary medicines Other contaminants 14

15 Regulation (EC) No 396/2005 What does this mean? In short: You can NOT draw the conclusion that: Regulation (EC) No 396/2005 is applied only when a residue is a residue of a plant protection product. Or in other words: 15

16 The pesticide regulation 396/2005 might be valid even if you find something in your food product, which is NOT a pesticide residue but entered into your food product by (process) contamination. And what does this mean for me? Maybe the 0,01mg/kg default value of the pesticide regulation 396/2005 will be applied for your product as well even for substances resulting from a contamination. 16

17 What makes it even more complicated... - Different EU-member states have different points of view how to interpret the Regulation (EC) No 396/ On a EU-level, Regulation related to contaminants also exist, f. ex. - - Veterinary medicines: Reg. (EC) No 470/2009 / (EC) No 37/2010 Biocides: Reg. 528/2012 / Directive 98/8/EC Contaminants: Reg. (EC) No 315/93 / Reg. (EC) No 1881/2006 Commitment for a harmonised EU-approach is limited (f. ex. Chlorate). - Alternative approach: Toxicological data (f. ex. Acute Reference Dose / Acceptable Daily Intake) are used for calculating the toxicological risks / exposures of of contaminants (PRIMo-Model). 17

18 Summary The evaluation of New Substances is not straightforward The cause / source is some kind of abandoned The application of pesticide Regulation (EC) No 396/2005 is (currently) not limited to pesticide residues only Substances, which enter the food chain via contamination might also be evaluated by according to the requirements of Regulation (EC) No 396/2005 (default value of 0,01 mg/kg) In terms of food safety (Article 14 Reg. (EC) No 178/2002): Toxicological assessments are performed (PRIMo-Model) 18
